Though his name didn’t appear on the lineup ahead of the event, Vedder became the highlight of the night as he performed a set of Pearl Jam staples, covers, and songs from his solo career. As Rolling Stone reports, Epstein joined Vedder on stage for renditions of “Better Man”, “Corduroy”, “Big Hard Sun”, The Who’s “The Kids Are Alright”, and Split Enz’s “I Got You”.

The highlight of the set — at least for Cubs fans — came when the duo performed beloved Cubs anthem “All the Way”. They were also joined onstage by Cubs manager Joe Maddon, former Yankees outfielder Bernie Williams, and the Smashing Pumpkins’ Jimmy Chamberlin for a raucous cover of Neil Young’s “Rockin’ in the Free World.”

According to Rolling Stone, Vedder also auctioned off an autographed guitar as part of the concert’s fundraiser auction, raising $26,000. All proceeds from the concert went to Epstein’s Foundation To Be Named Later, whose mission is “to raise funds and awareness for nonprofit agencies serving urban youth and families.”
